摘要 ：
Simultaneous partial nitrification, biological phosphorous removal and sludge fermentation in continuous-flow system faced many challenges in wastewater treatment plants (WWTPs). In this study, a novel process was developed to achieve partial nitrification, enhanced biological phosphorus removal and in-situ fermentation (PNPRF) in continuous-flow system dominated by Tetrasphaera treating low carbon/nitrogen ratio (COD/N) real domestic wastewater. After 80 days of operation, no external carbon was added into the influent. Nitrite accumulation ratio (NAR) reached 99.4% and removal efficiency of PO43- -P was 100%. The effluent concentration of total inorganic nitrogen (TIN) was lower than 2 mg/L. Compared with traditional biological nitrogen and phosphorus removal processes, the daily sludge discharge in continuous-flow PNPRF decreased by 61.9%. DNA concentration of the sludge supernatant after anaerobic zone was 2.26-fold of that before anaerobic zone, and percentages of intact cells decreased by 6.9% and necrotic cells increased by 8.3%, indicating that cell lysis caused the reduction of sludge discharge. The negative effect of prolonged anaerobic phase on transcriptional response of nxrB gene was more significant than that of amoA and hao gene, which resulted in stable partial nitrification. The activities of ammonium-oxidizing bacteria (AOB) were higher than that of nitrite-oxidizing bacteria (NOB), and reverse transcriptional PCR (RT-PCR) showed that RNA expression of AOB was higher than that of NOB. Achieving partial nitrification, enhanced biological phosphorus removal and in-situ fermentation in continuous-flow system dominated by Tetrasphaera solved the problems of carbon source deficiency and large amount of sludge discharge in treating real domestic wastewater process.

摘要 ：
Autotrophic denitrification has become the main contributor to the nitrogen removal from wastewater due to its high efficiency, safety and economy. Effect of Fe on sulfur autotrophic denitrification coupled to heterotrophic denitrification was investigated to enhance the nitrogen removal. Under the substrate ratios of S2O32-:Fe (II):CH3COO– of 1:1:3, 1:3:1 and 3:1:1, the microorganisms were wrapped by Fe minerals, and the normal metabolic pathways were blocked. By adjusting the substrate ratios of S2O32-:CH3COO– of 1:3, 2:2 and 3:1 without Fe (II), the denitrification recovered with the removal efficiency of NO3–-N to 99%. Insufficient addition of S2O32- and CH3COO– promoted the production of NO2–-N and N2O with high percentage of N2O of 5.70%. When S2O32- and CH3COO– were sufficient, the nitrogen removal was effective and N2O production was low (1.35%). Modified Blotzman model and Logistic model were suitable to describe the removal of NO3–-N, modified Logistic model was suitable to reveal the generation of SO42-. Dechloromonas acted as denitrifying bacteria in substrate ratios of S2O32-:CH3COO– of 1:3 and 3:1 up to 58% and 56% at the genus level. Autotrophic Thiobacillus bacteria decreased from 19% (inoculated sludge) to 1% (1:3), 16% (2:2) and 17% (3:1), respectively. Thauera was corresponded to the heterotrophic denitrification which was successfully enriched from 0 (inoculated sludge) to 13% (1:3), 49% (2:2) and 2% (3:1). The different substrate ratios promoted the coexistence of autotrophic and heterotrophic bacteria and cooperated with Fe minerals to improve nitrogen removal from wastewater. © 2021 Elsevier B.V.

摘要 ：
Phosphorus is an indispensable element, while the existing phosphate rock resources are not enough to maintain the long-term demand of modern agricultural development. To ensure the sustainability of economic and social, it is necessary and urgent to seek the alternative phosphorus source of phosphate rock. In this study, calcined clam shell powder (CSP) was firstly used as a modifier and mixed with sewage sludge (SS) for co-pyrolysis to obtain sludge-derived pyrochars containing a large amount of bioavailable phosphorus. The effect of different temperatures (500, 600, 700, 800 degrees C) and dosages (0%, 10%, 20%, 30%) on the change in the form of phosphorus during the pyrolysis process were investigated. With the increase of temperature and the addition of CSP, the orthophosphate (Ortho-P) increased from 63.69% in the original SS to nearly 100%. Furthermore, the main phase of inorganic phosphorus (IP) changed, mainly in the form of apatite phosphorus (hydroxyapatite increased from 8.88% to 35.97%), and the concentration of easy-to-lose phosphorus reduced to 0.11 mg/g. After co-pyrolysis of SS with CSP, the passivation situation of heavy metals (HMs), such as Zn, Mn, Cr, Cu, Cd and Pb was significantly improved, thus reducing the potential environmental risk. The planting experiment proved that the sludge-derived pyrochars obtained by adding 20% CSP at 800 degrees C promoted the germination of seeds and the growth of seedlings. Consequently, the product of SS co-pyrolysis with CSP could be used as an excellently bioavailable and environmentally friendly phosphate fertilizer for agricultural production.

摘要 ：
As a novel phosphorus recovery product, vivianite (Fe-3(PO4)(2)center dot 8H(2)O) has attracted much attention due to its enormous recycling potential and foreseeable economic value. Taking sponge iron as seed material, the effect of different reaction conditions on the recovery of phosphorus in waste activated sludge by vivianite crystallization was studied. Through single factor tests, the optimal conditions for vivianite formation were in the pH range of 5.5-6.0 with Fe/P molar ratio of 1.5. Scanning electron microscopy (SEM), powder X-ray diffraction (XRD), and energy dispersive spectroscopy (EDS) were used to analyze the components of the crystals. The results showed that the vivianite produced by sponge iron as the seed crystal were larger and thicker (300-700 mu m) than other seed (200-300 mu m) and without seed (50-100 mu m). Moreover, vivianite, which was synthesized with sponge iron as seed, was obviously magnetic and could be separated from the sludge by rubidium magnet. The Box-Behnken design of the response surface methodology was used to optimize the phosphorus-recovery process with sponge iron (maximum phosphorus recovery rate was 83.17%), and the interaction effect of parameters was also examined, pH had a significant effect on the formation of vivianite. In summary, this research verifies the feasibility of using sponge iron as the seed crystal to recover phosphorus in the form of vivianite from waste activated sludge, which is conducive to the subsequent separation and utilization of vivianite.

摘要 ：
As a promising phosphorus source, phosphorus recovery from sewage sludge ash is necessary to ensure sustainable phosphorus cycle and management. To achieve these targets, a novel strategy including phosphorus capture by acid-resistant adsorbent from acid-extract of sewage sludge ash and repeated enrichment in eluent was first proposed in this study. Over 93% of phosphorus was extracted by H2SO4 acidification at pH of 2.0, and a tailored acid-resistant adsorbent recovered almost all the extracted phosphorus in acid-extract of sewage sludge ash. The fitting results of multiple models showed that the rate-limiting step for phosphorus recovery was chemical reaction, and the maximum recovery capacity of acid-resistant adsorbent was 41.7-44.0 mg/g. Characterization results of X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and Zeta potential suggested that the recovery mechanism of acid-resistant adsorbent for phosphorus included ligand exchange, inner-sphere complexation and electrostatic attraction. After 8 cycles of recovery-repeated enrichment, the phosphorus in eluent was enriched about 6.7 times. Over 99% of phosphorus in eluent was recovered as struvite by adding external magnesium and ammonium at pH of 8.5. The content of heavy metals in recovered struvite were far below the utilization standard of plant fertilizer, indicating that the phosphorus in sewage sludge ash could be recovered in the form of high-quality phosphorus fertilizer.

摘要 ：
The dual isotope fractionation of nitrogen (N) and oxygen (O) is an effective way to track the transformation of NO3--N in biological denitrification process. The Sulfur autotrophic denitrification combined with the different concentrations of S2O32- was investigated using the dual isotope fractionation of nitrogen (N) and oxygen (O) to reveal the nitrogen removal mechanism of the activated sludge. Based on successful autotrophic denitrification incubation, the modified Logistic model responded to the short-term effects of S2O32- addition on NO3--N removal and SO42- generation. Under the S2O32- addition of 0.5, 1, 2 and 4 times of the incubation stage (49.29 mg/L-394.32 mg/L), the fractionation effect of N in NO3--N ((15)epsilon(NO3)) decreased from 8.74 +/- 1.81 parts per thousand to 2.08 +/- 0.06 parts per thousand, and the fractionation effect of O in NO3--N ((18)epsilon(NO3)) declined from 11.34 +/- 0.46 parts per thousand to 5.48 +/- 0.46 parts per thousand. The (15)epsilon(NO3)/(18)epsilon(NO3) was maintained at 0.46-0.94, indicating a negative correlation between addition amount and isotope effect, and the addition of high concentrations of S2O32- was not suitable for system stabilization. Moreover, the O-18-labeled H2O (delta O-18(H2O)) tests significantly proved the presence of O exchange between NO2--N/NO3--N and H2O (67%/97%) during the nitrogen removal process, while the reoxidation of NO2--N was explored in the autotrophic denitrification. The kinetic models coupled with isotope fractionation effectively revealed the nitrogen removal characteristics in the autotrophic denitrification systems, and verified the difference between the activated sludge-based wastewater treatment process and the natural ecosystem.

摘要 ：
Achieving enhanced biological phosphorus removal dominated by Tetrasphaera utilizing waste activated sludge (WAS) as carbon source could solve the problems of insufficient carbon source and excessive discharge of WAS in biological phosphorus removal. Up to now, the sludge reduction ability of Tetrasphaera remained largely unknown. Furthermore, the difference between traditional sludge fermentation and sludge fermentation dominated by Tetrasphaera was still unclear. In this study, two different sequencing batch reactors (SBRs) were operated. WAS fromSBR-parent was utilized as sole carbon source to enrich Tetrasphaera with the relative abundance of 91.9% in SBR-Tetrasphaera. PO43--P removal and sludge reduction could simultaneously be achieved. The effluent concentration of PO43 --P was 0, and the sludge reduction efficiency reached about 44.14% without pretreatment of sludge. Cell integrity detected by flow cytometry, the increase of DNA concentration in the sludge supernatant and decrease of particle size of activated sludge indicated that cell death and lysis occurred in sludge reduction dominated by Tetrasphaera. Stable structure of activated sludge was also damaged in this process, which led to the sludge reduction. By analyzing the excitation-emission matrix spectra of extracellular polymeric substances and the changes of carbohydrate and protein concentration, this study proved that slowly biodegradable organics (e.g., soluble microbial byproduct, tyrosine and tryptophan aromatic protein) could be better hydrolyzed and acidized to volatile fatty acids (VFAs) in sludge fermentation dominated by Tetrasphaera than traditional sludge fermentation, which provided carbon source for biological nutrients removal and saved operation cost in wastewater treatment.

摘要 ：
Sponge iron is a potential material for nitrogen and phosphate removal. To explore the performances and mechanisms of nitrogen and phosphate removal by sponge iron, a sponge iron biofilter was established. The results showed that nitrate was completely removed at HRT of 48 h without external carbon source and at HRT of 3 h with C/N ratio of 5. Furthermore, it was easy to achieve partial denitrification at HRT of 1 h with C/N ratio of 3. The mechanisms of nitrate removal were chemical reduction and nitrate dependent ferrous oxidation without external carbon source and heterotrophic denitrification with external carbon source. XPS result indicated that phosphate was removed by the formation of ferric phosphate precipitation. High throughput sequencing showed that iron-oxidizing bacteria Gallionellaceae was highly enriched in biofilter, accounting for 17.83%, which indicated that it was feasible to achieve autotrophic nitrate removal by sponge iron biofilter.

摘要 ：
Preparing adsorbents with hydrated phosphorophilic metal oxide modified porous materials is a promising method for recovering phosphorus from wastewater. In this study, three kinds of adsorbents were developed by loading iron (), zirconium () and lanthanum () on diatomite under the same preparation conditions (referred to as D-HFO, D-HZO, D-HLO, respectively). The property differences and phosphorus adsorption behavior differences of three adsorbents in actual wastewater were explored. Characterization results indicated that three metals were mainly supported on diatomite in the form of hydrated oxides with nanostructures. In batch experiment, the adsorption capacity of D-HFO, D-HZO was high under acidic conditions, while D-HLO tended to adsorb phosphorus in neutral or slightly alkaline environment. The maximum adsorption capacities of D-HFO, D-HZO, D-HLO to adsorb phosphorus from wastewater were 13.22, 20.25, 148.31 mg/g, respectively. Yet in fixed-bed column experiment, D-HLO particles agglomerated due to its high chemical energy, and the maximum treatment bed-volume (BV) of D-HFO, D-HZO, D-HLO were 120, 315, 210 BV, respectively. Langmuir-Langmuir fitting results showed that the chemical precipitation contribution rate of phosphorus adsorbed on D-HFO, D-HZO, D-HLO was 83.5%, 63.8%, 86.2%, respectively. Ligand exchange and surface complexation were the main recovery mechanisms in phosphorus adsorption process from the actual wastewater by three adsorbents. © 2021 Elsevier B.V.
